Improvement in cultivating-plows

Specification. forming part df Letters Patent No. 2.792, dated To all 'whom it may concern.:

Be it known that I, MARSHALL J. HUNT, of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Agricultural Instruments Denomiuated Cultivators,7 which im- `the Corn and Cotton Plow and Gulti'vator, and I do hereby declare that the following isa full and exact. description thereof. 1-

In my corn and cotton plow and cultivator lI use three cultivtor-teeth, which are aiiixe'd Apermanently to the frame by Wedges or screw-' nuts, and two teeth or mold-boards, which are attached to two sliding bars passing through a mortise atthe rear en d of the frame, which bars are retained in place by wedges. or otherwise, sowas to admtot the placing of' the teeth or ofthe mold-boards which are attached to'thcin at such a distance apart as shall adapt them to the rows of corn, cotton, or other `article under cultivation, and which admit, also, of the shifting ot the mold-board, so as to turn the earth either outward or inward against the plant. lalso make the drawing-'bar or tongue, to which the horse isattached, to rise orfall in such manner as to determine the depth to which the `cultivator-teeth shall enter the ground. y

In the accompanying drawing I have given a. perspective representation ot' my improved. cultivator and plow.

A A. are the sides of the frame,'and. B B the handles, Whichare similar to such as have been before known and used.

C QC are thethreepermanentteeth, to which any of the usual forms may be given, as may y be preferred.

D D are two slidingbars, which pass through mortises in the sides A A ofthe cultivator, each of them carrying at its outer enda tooth or a mold-board, as the nature of they case may require, which teeth or mold-boards-,may be placedat any desired distance apart, 'and are September 30, 1842.

to'bc held in place by wedges or screws acting upon the sliding bars. l

E'is thedrawingbar or tongue, to which a singletrec is to be attached. This bar is fastened by a staple to the cross-piece F of the.

frame, and near its` fore end has a mortise through it,which G, fixed to theframe, and havingholesthrough it admitting of a boltor bolts to setthe tongue at any required height. 4,'

' This instrument may be varied in size; but those which I have used have been from four to tive feet in length, and the frame at the rear end about two feet and a halt wide. The teeth which I have used spread out about six inches wide at the bottom, and are about six inches deep. The mold-boards I have made `about t'teen inches long and from six to nine inches wide. All this, however, may be varied accordingl to the nature of thev soil or the judgment of the user. l

My general mode ot' proceeding is vto use the ve cultivator-teeth until thecorn or other vegetable requires plowing or hilling. I then remove the cultivator-teeth from the sliding -bars an-d replace them by two mold-boards,

setting the bars so that the mold-boards shall stand at the desired width apart and Areversing the faces of said mold-boards and their distance apart, so as to plow alternately within `and without the respective rows! Havingthus fully'described the nature of'my improvements in the corn and cotton plow and cultivator and shown the mannern which the samel operates, what I claim'thcrein as new, and desire to secure by Letters Patent, is

The employment of twosliding bars, carrying two cultivator-teeth or two mold-boards, which may be shifted and set'in the manner l'and for the purpose set forth.
